The blocking of senders, and the reporting messages as spam or phishing, is only available is Mimecast for Outlook v6.3 or later.

When you select a message either in Microsoft Outlook, the Mimecast for Outlook Online Inbox, or the Mimecast for Outlook search results, you can perform the following actions:

  • Block a sender's address or domain. This added the sender's address or domain to your personal blocked senders list.
  • Report the message as spam or phishing. This automatically triggers the following actions:
    • The message is moved to your Junk E-Mail folder in Microsoft Outlook.
    • The sender of the message is added to your Blocked Senders list.
    • The message is forwarded to the Mimecast Security Team for analysis.


The actions above can be performed from a number of different locations as outlined below:
